This serie aims at bringing support to mainstone board on a device-tree based build, as what is already in place for legacy mainstone. The bulk of the mainstone "specific" behavior is that a u16 write doesn't work on a address of the form 4*n + 2, while it works on 4*n. The legacy workaround was in SMC_outw(), with calls to machine_is_mainstone(). These calls don't work with a pxa27x-dt machine type, which is used when a generic device-tree pxa27x machine is used to boot the mainstone board. Therefore, this serie enables the smc91c111 adapter of the mainstone board to work on a device-tree build, exaclty as it's been working for years with the legacy arch/arm/mach-pxa/mainstone.c definition. As a sum up, this extends an existing mechanism to device-tree based pxa platforms.
